Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2026-35-ALF is determined by strict equivalence across the following critical parameters:

• Voltage - DC Spark Over (Nominal): 350 V
• Impulse Discharge Current (8/20µs): 20000A (20kA)
• Tolerance: ±20%
• Number of Poles: 3
• Fail Short characteristic: No
• Package / Case: Cylinder No Lead, 3 Terminal
• Mounting Type: User Defined
• RoHS and regulatory compliance status

The substitute part 2026-35-A1LF meets all these criteria and belongs to the same TRIGARD® 2026 series, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 2026-35-A1LF is the direct substitute for the obsolete 2026-35-ALF. Both components are manufactured by Bourns Inc. within the TRIGARD® 2026 series and share identical electrical ratings, mechanical packaging, and regulatory compliance certifications. The primary distinction is product status: the 2026-35-A1LF maintains active production status, ensuring availability for new designs and system replacements. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99, meeting equivalent regulatory requirements for deployment in equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can the 2026-35-A1LF be used as a direct replacement for the 2026-35-ALF in existing designs?

A: Yes. Both components share identical electrical specifications (350V DC spark-over, 20kA impulse discharge current), mechanical packaging (Cylinder No Lead, 3 Terminal), and regulatory compliance status. No circuit modifications are required.

Q: What is the primary reason for substitution?
